WATERPROOFING COMPOUND.

Specification of Letters Patent.

Patented May 14, 1907.

Application filed November 23, 1903. Serial No. 182,402.

Be it known that we, Auor's'r Gnoss and AARON CHARLES IlonN, citizens of the United States, residing in Manhattan borough, city of New York, in the county of New York and State of New York, have invented a certain new and useful \Vaterproofing Compound, of which the following is a specification.

This invention relates to a waterproofing or danurprooiing coat or paint for application to buildings and other structures, either inside or outside. lleretoi ore tar has been employed for such purposes, but it is well known that by the application of the necessary heat} to convert it into liquid and usabletorl'n, the oils contained therein are driven oil, leaving only the gum, which, upon subsequently, coohng and being exposed to an,

disintegrates, powders and chips. Moreover,

thctar can be heated and applied only by skilled labor, and the expense 1s so great as to amount to a SQX'lOIlS'OhJOC-l lOl'l to its use.

The present invention consists of a com- 1 pound which can be supplied in liqu d form,

and may be applied. cold and by means of unskilled labor. Said compound consists of asphaltor asphaltum, mixed with sull'icient pine oil to render thecoi'npound liquid, and also with sullicient linseed oil to tho; the as phalt and the piueoil, Portland cement being added to render the compound better adapted for its pur )ose.

Preferably asphal tum of a high grade is boiled and refined, the heatrequired being about 400 Fahrenheit. It becomes a thick liquid, into which linseed oil is slowly poured. Then inc oil is added, and the compound is stirred until it is thoroughly mixed. The pine oil is a non-drying oil, and the compound remains liquid for a long time. Portland cement is usually added shortly before the compound is to be applied to a floor, wall or roof.

By the refining process, the 'asphaltum is deprived of its impurities, and as well of acids and oils. The addition of the pine oil, which is preferably distilled fromtlie .P'i'rius Austral'is, renders the compound plastic or liquid. The linseed oil favors the iluxing of the asphaltum and pine oil. One of the advantages pertaining to the use of Portland cement is that it gives the mixture body; While the other ingredients prevent breaking and cracking after application to a building.

The compound is not only damp proof, but.

acts as a tiller for crevices or holes in the wall, floor or root". it is recon'nnemled that the pine oil and linseed oil be in about. equal pro- The compound may be applied cold, by us.

ing a suitable brush, and owing to its plastic property, it remains elastic for an imlelinite length of time, and will not powderor (lake. Specialists not being needed, as the compound may be applied by anybody, the cost of water-proofing is reduced considerably. Tarred felt, or other waterpnmiing sheeting,

adheres readily to the compound. aft-er the latter is applied to a floor, wall, roof or other place, so that it is practicable to apply as many thickl'icsses of felt as may be desired, in alternation with coatings or layers of the compound. If desired, wall-plaster or any other mortar may be. applied directly upon the compound, after the latter has set suili ciently.

The invention is not limitcd'to the spec-inc. ingredients above -forth. Substitutes for asphaltum are coal tar, pitch, etc., either separately or mixed. Other bituminous material maybe used as a base. Other oils may be used, such as fish oil or parailin. One advantage of mixing a bituminous material with a non-drying or sh'iw-drying oil, is that the mixture may be ap lied cold, and will not subsequently crack or lake. Plaster ofparis or other cement may in some instances be used in place of Portland cement, although the latter is preferred. It will be understood that the -1naterials compounded as above Ins ' dations of these buildings.

. the compound will stand pressure, is impervious to water and never breaks in actgal use even under the severest conditions.

The compound is specially adapted for substructure work, such as the foundations and walls of the modern high office and storage buildings, underground tunnels &c. It is a well known fact that the foundations of these high buildings, where they have two or three stories below the surface of the ground, are constantly surrounded by water. The compound is specially adapted for preventing the water penetrating through the walls or foun- The compound is applied during the construction of the foundation, and the top of the foundation is thoroughly coated with the compound prepara tory to building the walls thereon. The Walls are then built up and rest on a coating or film of the compound, which does not crack or disintegrate under the great pressure and,weight of the walls, and forms a thoroughly tight Waterproof joint. The compound is also applied to the wallsof the stories below the surface ofthe ground, and asthe film remains plastic it will stand the pressure of the earth packed against it, and prevents the water from penetrating through the walls, thereby keeping the underground stories of the building erfectly dry.

aving thus described our invention, we claim:

1. A waterproofing fluid comprising asphalt, cement, pine oil for keeping the mixture in a fluid condition, and an'pil which serves as a flux for said oil.

2. A Waterproofing fluid comprising asphalt, cement andfpine oil.

3. A waterproo ng compound comprising asphalt, cement, pine oil and a flux.

4.. A waterproofing compound com rising asphalt, cement, pine oil and linseed oi 5. A waterproofing compound comprising asphalt and cement in about equal proportions, mixed with pine oil and linseed oil, the pine oil and linseed oil being in about equal proportions and forming about one-fourth by weight of the compound.

6. A waterproofing compound comprising asphalt and cement mixed with sufficient pine oil to render the mixture plastic, and with sufficient linseed oil to form a flux for the pine oil.

7. A water roofing compound comprising asphalt, Portl and cement, pine oil and linseed oil in the following proportions by Weight: about 120 pounds of pine oil, about 120 pounds of linseed oil, about 500 pounds of asphalt, and about 475 pounds of Portland cement.

8. A waterproofing compoundof asphalt, Portland cement and. pine oil.

9. A waterproofing compound of asphalt, Portland cement, pine oil and linseed oil.

10. A waterproofing compound of asphalt, Portland cement, pine oil and linseed oil, the linseed oil and pine oil being in about equal proportions, and forming less than half by weight of the compound.

1]. A water roofin fluid comprising as- ,phalt and suf 'icient ine oil to render the compound permanent y'plastic after applicati on to a surface.

12. A waterproofing compound comprising asphalt, sufficient pine oii to render the compound permanently plastic after application to a surface, and. a flux.

13. Awaterproofing compound comprising asphalt, sufficient pine oil to render the compound permanently plastic after application, to a surface, and linseed oil to serve as a fiuxjgf HERMAN M. Sonoor;
